Streptococcus pneumonia is the leading cause of bacterial pneumonia. It can enter your lungs through inhalation or through your bloodstream. There is a vaccination for this type. Haemophilus influenzae is the second most common cause of bacterial pneumonia.
The droppings are similar in color to the wood residue that the insects spill as they eat. Subterranean termite droppings are soft and used in constructing nests, whereas drywood termite droppings are hard and look like piles of sawdust, according to Extension.org.
Though fumigation kills all termites inside the house, the droppings will still be inside the termite galleries or tunnels inside the wood. Through constant movement of the house, for example, doors closing hard, natural movements, and the gravitational pull, you will still see termite droppings occasionally.
